hello,

I am trying to get a random MC to play every 15 seconds. Using setInterval.

Here is my code \>  
What seems to be incorrect is that the setInterval doesnt seem to be collecting the function which starts the MC.

function car1(){  
car\_mc.\_x = 1130;  
car\_mc.tween("\_x",-300,4,“easeinSine”);  
}  
function car2(){  
car\_mc.\_x = 1130;  
car\_mc.tween("\_x",-400,4,“easeoutSine”);  
}  
function automob(){  
var ran:Number = Math.ceil(Math.random()\*2);  
carran;  
trace (ran);  
trace (car[ran]);  
}  
setInterval(automob,15000);
